Marine Corps Doctrinal Publication 1 (MCDP-1), Warfighting is the foundational document that communicates the keystone philosophy for the Marine Corps. It provides the basis for all learning within the Marine Corps and is as valuable to a private as it is for a general. Every officer must read and reread the text, understand it, and take its message to heart. The philosophy contained in this publication has influenced the Marine Corps’ approach to every task. MCDP-1, Warfighting states, “Was is both timeless and ever changing. While the basic nature of war is constant, the means and methods we use evolve continuously.” As war evolves, so too must those who are prepared to wage it. It is the responsibility of every officer to study, understand, and apply the principles of MCDP 1.
